K8064 RED error LED

Can the Velleman people explain how the fase shift detection works on this KIT ?

I have multiple working perfect at home but one fails after some time. ( 4 times blinking RED LED )
When reset this dimmer by disable and enable power again this works OK for ??? time, and then fails again.

Is it possible to disable the fase shift detection ?

Has Velleman a better Kit that does what its specified ?
And works with an inductive load ( ringcore trafo of max 400W ) that drives 6 x 12V50W lights ?

kind regards, Bart
